J. S. BURNS PACKING BOX Filed Aug. 14, 1933 2 Sheets-Sheet 2 Patented Sept. 3, 1935 corporation of Michigan Applicafioh August 14, 1933. Serial No.- 684,989,

v a (o1'.229---15) v This invention relates to a boxz'zonstruction andmore particularly to a carton formed of cardboard and having separating partitions therein.

of only two members, the outer member being bent to form a box of rectangular shape and the inner member, of rectangular cross section, extending between the sides of the box as will be later explained.

One of the primary advantages of my invention resides in the durability and strength of the box, the partitions thereinbeing in the form of a hollow strut which extends between the opposite sides of the box to prevent crushing thereof, the sides of the reinforcing member serving as the separating partitions. Also, the other two sides of the reinforcing member extend between the end flaps of the exterior box construction and tend to prevent endwise compression of the box. Thus the box is strengthened and reinmerely having glue applied to its lower face and Fig. 4 is a perspective view of the partition member, and

Fig. 5 is an enlarged sectional view of the corner construction of said partition member.

Similar numerals refer to similar parts throughout the several views.

Referring to the drawings, numeral l indicates one end of'the box, numeral 2 the other end, the first mentioned end having an upper flap 3 and a lower flap 4 and the second mentioned end having an upper flap 5 and a lower flap 6. Sides 1 and 8 are provided, the former having an upper flap 9 and a. lower flap I0 and the latter having Briefly described, my improved boxis formed Y stapled at I4 to the end portion 2.

an upper flap H and .ai'lower flap l2- Also, the side 8 maybe provided with a tab l3 staple'dto the end 2 as indicated at M. See' Figs. 1 and 3; 1

, As clearly shown in Fig. 2, the end flaps 3, 4, 5, and 6 are of relatively short construction where- 5 by they fail to abut oneanother, their length being such that approximately one-third of the length of the box lies between their respective ends- Referring now to Figs. 4 and 5 a reinforcing f partition is shown, this partition consisting of 1.0 a bottom member l5, side members 16 and I1 and top flaps i8 and IS. The width of the bottom portion I5 is substantially equal to one-third of the length of the box and the lower face of this portion is adapted to have glue applied thereto after which it is inserted in position, see Fig.2, against thelowerfiaps I0 and I2 of the side members I and 8, the portion l5 having itstop surface in the same plane as theupper sides or faces of the end flaps 4 and 6', thus providing a 20 bottom for the box in a single horizontal plane. The juncture between the several folded portions in the reinforcing partition member are formed as shown in Fig. 5, that is, material is creased along the desired line and then is folded with said crease or score on the outside of the member.. This crease or score is indicated by the numeral 20.. This construction, as clearly shown in Fig. 5, prevents any bulging of the members l1. and I8 I at their corner and thus the reinforcing partition member is securely and. easily located inits position, the lower face of the bottom member I5 lying in secure contact withthe flaps l0 and I2 therebelow and the upper portions l8 and IQ of .-this same member lying flatly against the'upper cut to size, the sheet forming the exterior portion 6 of the box is folded to shape, the tab l3 being- Next, the lower side of the end flaps 4 and 6 may have glue 1 applied thereto and receive the upper faces of the lower side flaps i0 and i2 thereagainst. The ar- 5' ticles to be carried by the box, such as the cylindrical cans 20 shown in dotted lines in Fig. 2 and in full lines in Fig. 3, may be inserted at each end of the box.

Next, the bottom face of the reinforcing memher has glue applied thereto, as previously described, and then is inserted downwardly into the I box as clearly shown .in Fig. 1, cans 20 being I placed between the partitions i6 and II. This completes the packing of the box.

The box is now closed or sealed by folding the portions I8 and I9 inwardly toward one another so that they liein the same plane and'thus their edges come into abutting relationship. Glue, if desired, is applied to their upper surfaces and also may be applied to theupper flaps of the end members I, and 2 if these members are folded inwardly toward one another.- It will be noted that the ends of these flaps 3 and 5 abut against the extreme upper edges of the partitions I6 and- I1 and thus prevent their separation. The side flaps 9 and I I are now folded inwardly and downwardly and the sealing operation is now'complete.

Thus it will be seen that the reinforcing parti- I From'th'e above necessarily short description it will be appreciated that my construction although of relatively simple character, being formed of only two sheets of material, nevertheless provides a carton sub-divided into three equal parts thereby greatly strengthening the same andpreventing damage of the goods in transit as well as facilitating the packing of the goods. 7 n

. Without limiting myself to the particular embodiments of my invention illustrated and ex- .plained above, and desiring to protect my invention in the broadest manner legally possible, what I claim is:

abutting against each'other, said partition member having a length equal to the width of the box and extending between and abutting against the "said sides of thebox, said top members of "thepartition being glued to one face of the box for the purpose described.
